A Grid defines a particular type of technological and organizational interactionwithin a computational network, describing supply and demand for computationalor data services[1]. However, Service providers usually have more informationabout quality or availability of the services they provide,...

This paper examines the role of policies in different grid environments. A Grid technology becomes standardized and stable, various business models are envented and increasingly applied, and economic implications can be observed.Asymmetrically distributed information may allow for opportunistic...

The increasing interconnection between computers through the Internet has emergedthe vision of Application Layer Networks. Application Layer Networks comprise anabstract view on overlay networks (e.g. Peer-to-Peer networks, Grid infrastructures) ontop of the TCP/IP protocol. Their common...

This deliverable describes the work done in the first 6 months of task 2.1, " Software components:Specification and design of software components, based on theoretical and experimentalexperience from related and the assessment projects, so that Catallaxy can be implementedin any computational...

This deliverable describes the work done in task 3.1 “Implementation of additionalservices for economic enhanced platforms in Grid/P2P platform: Preparation ofconcepts and mechanisms for implementation” from the WP 3, “Proof-of-ConceptApplications”. The document is divided in five parts:...

Considerable efforts have been made developing software architectures which allowclients to obtain service “on demand”. The service-oriented architecture (SOA) based onweb service technologies provides a fundamental concept for this purpose, and is oftenadopted in current Grid implementation...
